The idea of exotic tachyon matter originates from the instability and decay of objects called \(D\) -branes
arising in superstring theories [1]}, [2]}. In the effective low energy limit, the potential is found to
have an unstable maximum corresponding to zero tachyon field. Sen [3]} showed that this is justified by
the fact that tachyons exhibit the property \((mass)^2<0\) . There is a phenomenon of rolling of the tachyon from
the unstable maximum to a stable average, expected value in the vacuum. This phenomenon finds applications in
cosmology [4]}, [5]}, [6]}, [7]}. However, our case is different as in the cosmological applications
time-dependent configurations of the tachyon field find use but here we will make use of spatially dependent
configurations [8]}, [9]}, [10]}. Wormhole supported by exotic tachyon matter for Ellis geometry has been
studied by Das and Kar [11]}. Wormhole with other forms of exotic matter at the throat has been studied
in [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}. Thin shell wormholes in heterotic string theory have been investigated in[19]}. A comparative analysis of thin shell wormhole construction in relativistic context and in the context of Horava-Lifshitz modified gravity has been carried out in[20]}. Wormholes have also been constructed using Chaplygin gas[21]} which is a fluid used in cosmology to explain the accelerating universe in the present epoch. Recently wormhole solutions have been obtained in the halo region of different galaxies which gives rise to the possibility of detecting a wormhole[22]}.
